Dave-H Posted February 1 Posted February 1 @Andalu @Cixert I think I've got things sorted out now. I uninstalled and reinstalled the Asmedia card on XP, and this time the driver installed correctly, so there's no more 'new hardware found' pop-ups. I'm not sure what went wrong the first time, but the extra 'IDE Controller' entry in Device Manager is no longer there, just the extra Primary and Secondary IDE Channel entries. It still seems to work fine. It even works in Windows 98, and I can now use my 2TB MBR disk in Windows 98 with the Paragon NTFS driver, which I could never do before as none of my other cards have Windows 98 drivers! Windows 98 doesn't see the 3TB disk of course as it's GPT. The only slight outstanding niggle is that the disks are not now recognised and mounted automatically when they are connected, either in XP or 10, but I can live with that. The Hotswap! program that I use to safely dismount the disks has a right click menu option to scan for new hardware, so I can just use that to manually mount the disks. The big test on the 3TB GPT disk will come later today when I do my monthly backup of my mobile phone onto it. That involves many thousands of files written very quickly, so if that doesn't trigger the corruption, nothing will! I can only do that now in Windows 10, as the backup software no longer supports XP, but I will be scanning the disk with CHKDSK in XP straight afterwards, with my fingers crossed. I will report back! Cheers, Dave. 2
Andalu Posted February 3 Posted February 3 @Cixert Good work I am continuing tests wwith some USB adapters and will post in the other thread (hopefully soon) I would like to ask you: with your USB adapters were you able to get GPT disk recognition? 1
Andalu Posted February 3 Posted February 3 @Dave-H I'm glad you solved that problem Please keep us updated about your test on the 3TB disk with the ASM1061 card. 1

Cheers, Dave. What model card did you buy? I get that it has an chip ASM1061. The photo you uploaded says SU-SA3004.v2. Is this a Ubit? 1 hour ago, Andalu said: @Cixert Good work I am continuing tests wwith some USB adapters and will post in the other thread (hopefully soon) I would like to ask you: with your USB adapters were you able to get GPT disk recognition? Great, I look forward to your results. I only achieved compatibility with +2TiB hard disks on the USB port with Windows 2003 drivers and USB adapters that specify a 4096 logical sector.

Dave-H Posted February 4 Posted February 4 OK, back again. I did my phone backup, and system ISO backups yesterday onto the 3TB disk, and everything still seems to be OK. I'm still getting the message about 'making corrections to the uppercase file' when I run CHKDSK on Windows XP, but this does not seem to be anything serious. I did some research on it, and this was stated about the 'uppercase file' - "Windows changed the uppercase file -- that's the one that provides translation between uppercase and lowercase, to preserve case-insensitivity for path names -- a little bit, between XP and Vista. You get this error if you formatted the drive under Vista or later, and are running CHKDSK under XP or earlier." So, it looks like it's just a difference between the way that XP records case information and Windows 10 records case information, nothing to worry about. So, no file system corruption problems as yet, and the drive does have more than 2TB of data on it. There seemed to be two key things here. Firstly, finding the right version of the Paragon GPT driver to use on XP, for which thank you @Cixert. Secondly, finding a SATA interface card which would work with the disk without causing corruption, for which thank you @Andalu. The card I'm now using, which is this one, appears as an IDE controller, not a SCSI storage device, and that seems to have been the key, because it presumably is exactly the same as connecting the disk directly to the motherboard, which also works. The seller's information on Amazon describes the 'no boot' mode on the card as 'data disk', which is exactly right in my case. Whether this would work with a disk that you wanted to boot from I don't know, but for my usage it's fine. The card I have is actually a version 1 card, not the version 2 card I posted the image of. The Amazon seller says you could get either version, but the only difference that I can see is in the PCI-E interface version, which doesn't seem to matter. The card is apparently branded 'Mugast' which is not a name I'm familiar with. The only thing I've lost is the automatic detection and mounting of the drive when it's powered up in its enclosure, which is not a big deal. I think this is probably because of the way that the operating systems now see its connection. I'm just glad that it works! I will of course report immediately if I do find any issues after prolonged use. Cheers, Dave. 2

Try to copy "gpt_loader.inf" in the "C:\Windows\inf" folder, re-install the paragon driver and then reboot. I just encountered the same behavior by connecting a GPT disk via eSata cable to the ASM1061 card. I solved in that way.
Dave-H Posted February 7 Posted February 7 Thanks, but it's exactly the same on Windows 10, where I'm not using the Paragon driver of course. I was thinking that it was due to the fact that it's an IDE controller connection, not a mass storage device connection. I can't remember whether it was the same when the disk was connected directly to the motherboard. Incidentally @Cixert my card is actually made by a company called SSU. There is very little about the card on their site, but is does look as if they only make the SU-SA3004 four port version, not the SU-SA3002 two port version. There's a driver download page, but not much else! 1
Cixert Posted February 10 Author Posted February 10 (edited) I have found a new problem working with GPT in Windows XP. Nothing serious if we take the appropriate precautions and also have Windows Vista updated or higher. I found it strange, since the error has not happened to me before. Right now I have the 6 Tb GPT hard disk to which I have only made a 1 TiB partition and left the rest of the space empty. When I open the Windows XP Disk Manager the partition disappears immediately, without performing any additional operation. To prevent losing the partitions I suggest making a partition table copy with Eassos DiskGenius from Windows Seven or higher in the menu Disk>Backup Partition Table. If you do not have a partition table copy, you can recover it with this same program from the menu Tools>Search for Partitions , choosing the Whole Disk option and in the search, clicking on "Reserve" when the appropriate partitions appear. If you know of another suitable program to make a partition table copy, please comment. The pity is that we need Windows Vista or higher or use a bootable CD with a program, since once the partitions are lost in XP the hard disk only shows a capacity of 1493 Gb, so we need to boot an operating system that recognizes the real disk capacity. Maybe it is possible from XP with DMDE, but I don't do it. Edited February 10 by Cixert
Dave-H Posted February 10 Posted February 10 I haven't seen anything like that happen so far, thank goodness. So you're saying that just going into the Disk Management on XP causes the partition on your 6TB disk to vanish? Does it not appear at all, or does it appear and then disappear? Presumably it's gone in Device Manager too?

I used Disk Genius in Win10 to create a single 1TB partition (1003GB) and then connected the drive to the ASM1061 card in XP: 1

I had previously posted this error with MBR partitions, but I can't find the post right now. On the 6TB GPT disk connected directly to SATA I created the first partition FAT32 1 GiB cluster 32 KiB aligned to sector 256 with Disk Genius on Windows Seven and then it disappeared just by entering Windows Disk Manager on XP. Now I have created more partitions and the error continues to occur. I will try with another initial sector size when I can empty the disk. If you can do the test with sector 256 and FAT32 cluster 32 KiB I would appreciate it. Edited February 17 by Cixert cluster 32 KiB

The other time I blamed the latest versions 11 and 12 of Minitool Partition Wizard, I don't remember exactly why, but these versions don't work well. Maybe once the partitions were created I formatted them with this one. I don't know, what seems clear is that I created them with DiskGenius since they start in sector 256 and Minitool starts them in sector 2048. If there is any news I will comment. And if anyone knows how Disk Manager deletes partitions just by starting the service, please comment.
